Fractional transport of bed-material load in sand-bed channels
… for predicting fractional transport rates of bedmaterial load in sand-bed channels. The proposed method is developed based on the concept of the transport capacity fraction (TCF) approach. The bed-material concentration for a given size fraction is obtained by weighting the bed-material …

monsters under the bed
The exhibition, monsters under the bed is a representation of what occurs when the bedroom lights are turned on and monsters, born from childhood fear, refuse to retreat into the shadows. Cartoon illustrations of physical and mental martyrdom point to the theme of death, as seen through the …

Flow, sediment transport, and bed topography in straight and curved gravel-bed channels
… shear stress variations in curved gravel bed channels. The flume experiments involved detailed measurements of bed topography, velocity, and sediment transport in both a curved channel and straight channel with and without an upstream obstruction. It was expected that the gravel bed …

Effect of Local Bed Hydrodynamics on the Distribution of Liquid in a Fluidized Bed
… Fluid CokerTM, liquid bitumen is injected into a bed of hot coke particles through spray nozzles, grouped in several banks at different vertical positions. The main objective of this thesis is to determine whether significant improvements in liquid-solid contact could be achieved by optimizing the …

Fluidized bed gasification of biomass
A fluidized bed process development unit of 0.8 m internal diameter was designed on basis of results obtained from a bench scale laboratory unit. For the scaling up empirical models from the literature were used. The process development unit and peripheral equipment were constructed, assembled and …

Heat transfer between a shallow fluidized bed and a single horizontal tube immersed in the bed
… a horizontal tube and a shallow fluidized bed of alumina particles (335-1261 micron) was measured, and the effects of the tube elevation (10-40 mm), static bed height (10-40 mm), and the design of the distributor were investigated. The cloud zone effect i.e. a sudden increase of the heat …

Fall Prevention: Responder 5 Bed Connectors
… fall prevention intervention, Responder 5 bed alarms, was explored. A literature review on falls was conducted to study the effectiveness of bed alarms. Capezuti et al. (2009) found bed alarms to be error prone and stress the importance of patient risk factor assessment and using bed alarms …
